I just downloaded the 64-bit Windows installer and even compared the md5 checksum, which is correct.
If the problem persists, I assume that you have network problems or some kind of a firewall issue...

Hi Thomas,
I have just got a new Windows 10 laptop, and have installed 32-bit DW, however I can't get the program to run. I don't get any error messages but after double-clicking the DW icon nothing happens. Java is up-to-date.
Any suggestions very welcome.
Tahnks,
Gavin.

Hi Thomas,
First of all thank you very much for your advice. I have successfully downloaded Datawarrior 4.7.2-64 for Windows. But now I have another problem that I can't run this program.

My computer is Windows 64-bit, JDK 64-bit is properly installed and configured, and it is also displayed in cmd.exe. However, each time I run datawarrior, the following two dialog boxes pop up. I don't know what it means. Do you have any suggestions?

your Java installation seems OK and is 32-bit. DataWarrior is 32-bit as well. Thus, the obvious things are OK. Can you open a command line window, cd to the DataWarrior installation directory in 'Program Files (32bit)' and then try to launch DataWarrior from there by typing 'datawarrior.exe'? Maybe you see an error message that tells us where to continue...

unluckily, I could just confirm that the current DataWarrior installation (4.7.2) for Windows is not compatible with the new Java 10 update. Evidently the JRE folder structure changes such that the java binary is not recognized anymore. Macintosh and Linux should not be affected.

We will try to get an update for Windows as quickly as possible. For the time being you may uninstall JRE 10 and use the latest Java 8 instead or just wait for the DataWarrior update.
